I think you are asking about a rare type of breast cancer called a angiosarcoma (this is a type of soft tissue sarcoma that can affect the breast) changing to an inflammatory type (cancer that affects the skin on the breast)
From what I understand about this type of cancer is that it is found in the breast tissue and also involves the skin at the same time. It is a feature of this type of cancer and may have something to do with how it grows and develops in the blood vessels. Women are usually diagnosed with this type of cancer when it is in the breast and also on the skin.
I am not sure if this is what you are asking about. So please get back to us if you need any more information or support. You may find it helpful to talk things through with one of the nurses on our helpline. The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.
